Question

For a giver input value c, the function f outputs a value y to satisfy the following equation -5 4y =-8 Write a formula for f(T) in terms ofT. fr) =

Answer 1

-5x-4y=-8

Solve for y:

-5x-4y=-8

Add 5x to both sides of the equation:

-5x-4y+5x= -8+5x

-4y =-8+5x

Divide both sides by -4

-4y/-4= (-8+5x)/-4

y= 2-5/4x

f(x)=2-5/4x
